Usage

Connect

const client = require("@oada/client")
const connection = await client.connect({
  domain: "api.oada.com",
  token: "abc"
})

GET

Single GET

const response = await connection.get({
  path: '/bookmarks/test',
  timeout: 1000  // timeout in milliseconds (optional)
})

Recursive GET

const dataTree = {
  "bookmarks": {
    "_type": "application/vnd.oada.bookmarks.1+json",
    "_rev": 0,
    "thing": {
      "_type": "application/json",
      "_rev": 0,
      "abc": {
        "*": {
          "_type": "application/json",
      	  "_rev": 0,
        }
      }
    }
  }
}
const response = await connection.get({
  path: '/bookmarks/thing',
  tree: dataTree,
  timeout: 1000  // timeout in milliseconds (optional)
})

Watch

A watch request can be issued by passing a callback function to watchCallback argument of a GET request.

const response = await connection.get({
  path: '/bookmarks/test',
  watchCallback: d => {
    console.log(d);
  },
  timeout: 1000  // timeout in milliseconds (optional)
})

Alternatively, one could explicitly send a watch request as follows.

const requestId = await connection.watch({
  path: '/bookmarks/test',
  rev: 1, // optional
  watchCallback: d => {
    console.log(d);
  },
  timeout: 1000  // timeout in milliseconds (optional)
})

To unwatch a resource, use the unwatch request.

const response = await connection.unwatch(requestId);

PUT

Single PUT

const response = await connection.put({
  path: "/bookmarks/test",
  data: { thing: "abc" },
  contentType: "application/json",
  timeout: 1000  // timeout in milliseconds (optional)
})

Tree PUT

const dataTree = {
  "bookmarks": {
    "_type": "application/vnd.oada.bookmarks.1+json",
    "_rev": 0,
    "thing": {
      "_type": "application/json",
      "_rev": 0,
      "abc": {
        "*": {
          "_type": "application/json",
      	  "_rev": 0,
        }
      }
    }
  }
}
const response = await connection.put({
  path: '/bookmarks/thing/abc/xyz/zzz',
  tree: dataTree,
  data: { test: "something" },
  timeout: 1000  // timeout in milliseconds (optional)
})

HEAD

const response = await connection.head({
  path: '/bookmarks/test',
  timeout: 1000  // timeout in milliseconds (optional)
})
